    Classpnp.sys error !Please Help!


    Hi,
    I am new to fourms and I would like some help. Basically I had a Windows 7 Home premium OS x64bit and it was working fine until I installed Windows 7 Ultimate on a separate partition on the same hard drive. Before i done that i changed the disk from dynamic to basic. After the installation was finished it did give me an error but I couldnt read it becuase the computer restarted. Now I have to wait 20minutes at the windows logo screen for both OS to load to desktop. When I use the safe mode it is getting stuck at Classpnp.sys for 20mins and loads. Also I am finding it hard to install my ATI display driver on the new OS as it is saying driver not supported. Any help is greatly appreciated and sorry for the long information.

    Here are my specs:
    Processor: Intel core i7 870 @ 2.93GHz
    Memory: 6144MB RAM
    VG Card: ATI Radeon HD 5570
    Motherboard: ipowerG5800 [I think]

    Thanks,
    Harry

Same story. Machine, in this case a Dell Inspiron 32 bit, suddenly refuses to boot. I can get as far as the login, hit a profile and the welcome screen hangs. Try to boot in safe mode and it sticks on classpnp.sys. I've scoured this and other forums for a solution and found only two. Reformat...

I was wondering if someone running Windows 7 Ultimate 64-Bit (RTM) would be willing to either zip or upload their Classpnp.sys file for me. Mine appears to be corrupt and I'd like to attempt to replace the one I have with a functioning one. It's located in C:\Windows\System32\drivers It...

Hi all, I need a heads-up. As recently as the other day, I switch the pc off normally, expecting the same as usual, blah blah, but the next day, on booting up, the system just hangs at the "Starting Windows" screen for no reason. Using safe mode don't work, hangs on the aforementioned file. I...
